Definitions

  • the object of the invention is to provide additional elementsi for such building sets so as to extend the uses thereof to include the construction of mechanical toys or models having rotating parts with gear wheel transmissions.
  • this object has been achieved by providing a special type of cog wheel, the features of which are defined in the claims and consist of a specific interrelation between on the one hand the pitch circle and the pitch of the teeth of the cog wheel and on the other hand the module of the building set.
  • FIG. 1 shows a gear wheel according to the invention viewed from one side
  • FIG. 2 the same gear wheel viewed from the other side
  • FIG. 3 presents a section along the line III--III in FIG. 1,
  • FIG. 4 shows a larger gear wheel viewed from the same side as the wheel shown in FIG. 1,
  • FIG. 5 shows part of a gear wheel in engagement with a building element acting as rack or lantern
  • FIG. 6 shows on a larger scale a section through a tooth at right angles to the plane of the gear wheel and tangentially relatively to the pitch circle
  • FIG. 7 shows a tooth section along the line VII-VII in FIG. 6.
  • the gear wheel shown in FIGS. 1-3 has 21 teeth T.
  • the gear wheel illustrated in FIG. 4 has 35 teeth, five of which are shown.
  • the gear wheel On the face shown in FIGS. 1 and 4 the gear wheel has a number of coupling studs P disposed symmetrically with respect to two diameters A and B which are disposed at right angles to each other and having the same module q as the coupling studs P on the outer face of the standard elements of a building set in which the gear wheel according to the invention is to be used.
  • Such an element E is illustrated in FIG. 5.
  • the radius r of the pitch circle D is nq, where n is an integer which in the gear wheel in FIGS. 13 is equal to 3 and in the gear wheel in FIG. 4 is equal to 5.
  • FIG. 4 the four coupling studs disposed next to the centre 0 of the gear wheel are designated P and their centers together form a square with the side q.
  • a chord through one side of the square parallel to the diameter A-A is designated C--C.
  • the number p of coupling studs in a row determined by one half of the chord CC and is, in FIG. 1 equal to 2 and in FIG. 4 equal to 4. It will be seen that the coeflicient it under the given conditions will be equal to p+1, the radius in FIG. 1 being equal to 3q, where p is equal to 2, and the radius in FIG. 4 being equal to 5: and where p is equal to 4.
  • the tooth module t is determined to be approximately equal to the module q of the building set, which will enable the gear wheel to be brought into engagement with a row of coupling studs P on an element E of the building set to form a rack and lantern pinion.
  • the tooth module t cannot be exactly equal to the module q of the building set because it is determined by the formula where T is the number of teeth and therefore must necessarily be an integer. However, if the number of teeth T of the smallest wheel is equal to 7, and t therefore will be equal to 0.9q, this approximation to the theoretical ideal will be adequate for all practical purposes.
  • This configuration of the tooth section which is a characteristic feature of the invention, makes it possible to bring a pair of gear wheels in closely accurate engagement, also when their axes are disposed at right angles to each other.
  • the cog wheels may conveniently be made by injection moulding of a thermoplastic material, and like the other elements they may be provided with both primary studs P at one face and secondary studs S, FIGS. 2 and 3, at the other face, the secondary studs S being so formed and disposed that each secondary stud touches the circumference of four primary studs P which together form a square.
  • a toy building set comprising a plurality of hollow parallel-sided blocks open at one face and closed at another face and adapted to be connected together by means of projections uniformly spaced apart and extending from the closed faces of said blocks, the distance between the axes of any pair of said projections constituting the module of said building set, a cog wheel element having a plurality of teeth, said cog wheel element having a pitch circle, the radius of said circle being an integral multiple of the module of the building set, and means comprising the pitch of said teeth whereby said cog wheel element can cooperate with the projections of said blocks in a rack and pinion relationship.
  • said cog wheel comprising a substantially flat disc-shaped element having a plurality of projections uniformly spaced apart and extending from one face of said disc element at a distance between their axes equal to the module q of the building set, and wherein the radius r of the pitch circle is determined by the formula r: (p+1)q, where p is the number of projections located at one face of the disc in a row determined by four projections symmetrically disposed with respect to the center of the cog wheel and adjacent to said center.
  • a toy building set comprising building blocks having at least one rectangular face provided withat least two rows of projections uniformly spaced apart in both longitudinal and transverse directions, the distance q between the axes of any pair of adjacent projections constituting the module of the building set, said building set also having at least one cog wheel characterized by the combination of the following features:
